THOMAS LAMB, OF BROOKLYN, NEW YORK.

STOPPER FOR' MILKfBOTTLES.

To all whom z't mayconcem I Be it knownthat I, THoMAsLAMB, a citi- V zen ,O f the United. States, residing at Brookf will be .nectedftogethe'i` and provided wi lyn, inthe county 0f Kings and State of N ew 4York,` have inventedjcertain new and useful Improvementsin Stoppers for Milkottles, of which the following is a specili-v 'cation, reference being had therein .to the accompanying drawing.

his' invention relates to Stoppers for milk bottles and has for its object the provision of an improved stopper of the` disk type which ture', capable of normally creating a doubleseal at the mouth ofthe bottle and possessing characteristics yfacilitating the removal of the stopper from said mouth. The preferred embodiment of the invention em'- braces'a pair of disks, one adapted to, fit a seat 'Within the mouth of the bottle, and the other to overli'e the mouth of the bottle to obtain the doublefsealing action to which I have alluded; the disks beingse arably conh attaching means enablingfthe use of either one independently. of the other, 'or the use of them together intact and the connection couplingl the two disks together enabling the inner disk to be withdrawn from the bottle under the liftinfr influence of the upper disk which is expose to the -manipulation of the user.

The above mentioned embodiment of the invention, so far as .thecharacteristic features mentioned.- areconcerned, as well "as the many improved details of construction and' arrangement of parts thereof,' will be readily understood. from the specific description hereinafter contained when read in con nection with the accompanying drawings,1

forming part hereof,wherein the device lconstituting said embodiment. is fully illustrated.

the disk C so as to overlie at its marginalv Y portion` Z the. upper edge a of the bottle mouth A. i

In keeping with my' conception, theidisks C and in a separable manner, will hereinafter appear, means will now be defined.

The disk C has separated from lbut allel with its upper surface a flat tongue E, disposed approximatelyy centrally of the disk, the same being" preferably of .metal having a tapered end e and a shank e which D are connected together,:preferablyI I I for reasons jwhich and the connectingv is bent, and'passes through thejmain or vbody portion of the disk C to the the latter, thence across the and upwardly againfthrough back4 beneath thetongue E,

under side of where the terunder surface l the disk and minal is pinched into firm holding engagement with the upper surface of the disk. In this manner,

the tongue is firmly secured l inplace by an integral part thereof, obvi-at- Y.

1ngthe necessity of supplemental fastening the shank through the reference to the disk. diate `portion of the shank below the body ofthe disk C which would expose. metal lto the bottle contents at this point is covered V10.5 devices'for the tongue,fand the passing of` ,v

disk at separated of the tongue with The lowr, intermeilo by a thin sheet of paper, paraffin or treated l as desired, this sheet represented at c constituting a layer or part of the disk C. The

Leemans ing depending enlargement on its bottom, and means for securing'the enlargement to the disk comprising a metal strip having its upper 4disk D has on its lower surface a i intermediate portion iniderlying'the enlargerelatively thick reinforcing rand spacing lmember F, of approximately oblong contour adapt-ed to separate Athe disks C and D, and

to facilitate the forcing of the disk C- to its seat B. This member F is secured in place by means or a flat strip of metal, the intermediate portion Gr of which underlies the member F and constitutes an eye for the introduction of the tongue or hook E of the lower disk. The terminal portions g of the eye G are passed upwardly through the spacing member F and through the main or body portion of the upper disk D, and then passed outwardly over the upper surface of the disk and substantially beyond .the edges of the latter to constitute flexible extensions g', those portions of the terminals g which directly overlie the disk D being held in place down against the disk D by a thin piece of paper el. The purpose of the free flexible extensions g is to provide a means adapted to be bent down around the bead at the bottle mouth to provide an additional fastening means for the stopper to hold the same in place, and to provide an extension adapted to be grasped by the fingers to pull the stopper out of the mouth of the bottle. These extensions are also useful in enabling the employment of the top disk D alone as a cover for the bottle, after the inner stopper c has been forcibly removed and discarded, 'as when but a portion of the bottle contents has been used.

lt is the purpose to hook the lower disk C tothe upper disk D, and then force the stopper into the mouth of the bottle, the relatively stid member vl? under pressure causing the lower disk to enter thebottle` mouth and seat itself in the retaining groove B, notwithstanding the bendingy tendency of the marginal portions of the lower disk C. it will be appreciated that, as an incident to forcing the lower disk in place the upward bending of the margin of the same tends to expel the air between'the two disks, and when the disk C finally springs into the groove B, with the attending separation of the disks, a vacuum or partial vacuum is formed in the space between the disks which acts to seat more firmly the upper disk on the edge of the bottle mouth to prevent the entrance, and to prevent the settling of dust and the like on the lower disk C.

lVhile I have herein disclosed a specific embodiment of my invention it will be apparent to persons skilled in the art that the invention is capable of embodiment in other forms and devices.

I claim:

1., ln a bottle stoppena disk member havment rand its terminal portions passed upwardly through the enlargement and through the disk and thence bent down upon the disk, one of the terminal portions extending outwardly beyond the disk to constitute a flexible extension, substantially as described.

2. ln a bottle stopper, a disk member having a depending enlargement on its bottom, and means for securing the enlargement to the disk comprising a metal strip having its intermediate portion underlying tue enlargement and its terminal portions passed upwardly through the enlargement and through the disk and thence bent down upon the disk` one of the terminal portions extending outwardly beyond the disk to constitute a flexible extension, said intermediate portion being spaced from the under surface of the enlargement to constitute an eye, substantially as described.

3. A stopper of the character described comprising disk members having separable coupling portions therebetween, said coupling portions being releasableby an edgewise movement of one of the disks relative to the other.

nfl. A bottle stopper of the character described comprising ay pair of disks. and separate fastening portions on said disks adapted normally to be engaged within the space between the disks and to be uncoupled to release one disk from the other, `substantially as described.

. 5. A bottle stopper of the character described comprising' a pair of disks, separate fastening portions' on said disks adapted vnormally to be engaged within the space between the disks and to be uncoupled to release one disk from the other, and spacing means interposed between the tvvo disks, substantially as described.

6. In a bottle stopper of the character described, a detached disk member adapted to lit a bottle mouth and provided with a tongue projecting above its upper surface and substantially parallel to the upper surface of the disk but spaced from` said sur face, said tongue having a shank 4passing through the body of the disk and beneath the same, in combination with a protecting layer underlying the bottom portion of said shank adapted to face the contents of the bottle, substantially as described.

7. A bott-le stopperof the character described comprising a pair of disks separably connected together, the connecting means between the disks consist-ing of a hook and eye connection, the eye comprising an integral continuous metallic strip having its middle portion directly underlying and spaced from the disk to which it is attached to provide an eye disposed transversely of said strip and between the same and the disk, the terminal portions of said strip being passed through and bent upon said disk, substantially as and for the purpose described.

S. A bottle stopper of the character described comprising a pair of disks separably connected together, the connecting means between the disks consisting of a hook and eye connection, the eye comprising an integral continuous strip having its intermediate portion spaced from the disk to which it is attached, and terminal portions passed through said disk, an end of one of the terminal portions being free to constitute a flexible extension adapted to fasten the disk to which it is attached in place, substantially as and for the purpose described.

9. ln' a bottle stopper, a disk member having a depending enlargement on its bottom, and means for securing the enlargement to the disk comprising an integral continuous metal st-rip having its intermediate portion underlying the enlargement and spaced therefrom to constitute an eye disposed transversely .of the strip,l the -terminal portions of the strip being passed through the enlargement and through ,the disk, subst-antially as described.

In testimony whereof I aix my signature in presence of two Witnesses.
